These were rated the No 1 budget headphones you can mix with, these are not meant for listening pleasure, not that they don't sound nice, but if you're looking for heavy bass, buy beats by dre! These are flat typically for monitoring, they're not gorgeous, but they really are quite truthful and extremely comfy, seriously recommended for pros on a budget!
I've been using these headphones for a week, i just finished treating my room with bass traps and absorbers, what really amazed me was how very similar my studio monitors and these headphones now sound. I did an 8 hour audio post final mix overnight with the headphones, the final mix was very good indeed, my client was blown away completely, no ear fatigue, no aches on my head or ears. Forget about these being pro budget headphones, they're good period!!
